Ruins of the Good Old Lost Age

Your fantasy characters found something which informs the audience this is a post-apocalyptic story! You hack! But what is it? Unearth your random number generator, a technology soon to be lost in the flames, and find out.

1. Television set
2. Gas station
3. Gun
4. Office building
5. Modern doctor's office
6. Gun (futuristic)
7. Library
8. Lincoln Memorial ~~~Bonus chance! Pick twelve countries from an atlas and roll again, then look up twelve landmarks and roll a third time.~~~
9. Amazon warehouse
10. Tank
11. Scuba gear
12. Fancy modern bow

The twelfth would be the most impressive to your characters, but that doesn't mean they should get it. Life's funny that way.

Addendum

"But will the streets be wide enough for tanks, given that they'll be designed for either foot traffic or efficient self-driving routes?"
I hadn't thought about it. I suppose it depends on whether the mastermind with the one tank landed the contract for road-building beforehand.

Military Self-Sufficiency

I just realized that future space colonies probably won't have tank factories and, therefore, no tanks. The crime gang or evil business that manages to put one together will rule the streets.

Big News!

People are still reading fantasy! I'm not sure they should, though. We should be living it by now. Does anyone think the major governments of the world don't control portals into other realms full of magic and exotic materials? That's why they aren't building cooler tanks.

Future Automotive Aesthetics

In World War II, people tried out all kinds of tanks, but now they're more or less all the same. Will that happen to cars? Should our science fiction settings have personal car, bulk cargo car, armored car, and nothing else? Or will they have more varieties than ever because improved industrial capacity will make more particular designs possible? I think the former, but I don't care about cars at all.

Negative Howling, for Example

Many think that just because their characters are fighting with tanks or spaceships that they can't have named special attacks. They couldn't be more wrong.

Addendum

The answer is a tank with pulsating Knight Rider lights.

Science Fiction Troubles

It's easy to imagine a better skyscraper or spaceship, but what's a better tank? They're already perfect.

Crypto-Post-Apocalypticism

The next time you start to delete a reference to the Battle of Kursk once you realize that you're writing about a medievalish fantasy setting, think twice. The implications of having your narrator know about armored fighting vehicles will send your readers reeling.

How to Level Up Your Story

Tank? Supertank.
King? Superking.
Mangonel? Supermangonel.
Cilious? Supercilious.

Always remember. Your audience won't know how great everything is unless you say so.
